sum 09$ 12 PATENTED 1 SHEH 100? 12 PAIENIED Jul 10 SKI! 12G 12 TIMEPIECE INDICATING TIME BY GENERATED IMAGES IN SETS BRIEF SUMMARY OF THE INVENTION The present invention relates to a timepiece which indicates the time by respective numbers of images in sets generated on its indicating panel and eliminates the requirement for hands and dial or numerals.

The conventional timepiece having hands and dial has the inherent disadvantage that it is difficult for small children to learn to read the time. A small child having average intelligence may be able to count at only three years of age, while a five year old child may still not be able to read the time on the conventional timepiece. The digital clock has a similar disadvantage, but to a lesser degree. In contrast, the timepiece of the present invention can be read by a child who can only count.

The main object of the present invention is to provide a timepiece in which both the hands and dial and the monotonous indication by numerals are eliminated, and wherein time indication is by its image arrays which can be decorative by themselves.

The images to indicate the time in the timepiece of the present invention can be generated by electrical means and no mechanical devices may be required. Hence, the present invention gives electrical and electronic engineers a great incentive to bring their latest achievements into timepiece designing. The present invention may thus enable the production of a genuine electronic watch consisting of solid state components only.

SUMMARY OF THE INVENTION Briefly, the timepiece in accordance with the present invention generates at least two sets of images on an indicating panel. The number of images present and belonging to the first set indicates the hourly segments in the designation of the time, and the number of images present and belonging to other one or two other sets of images indicates the minute segments in the designation of the time. Each image is explicitly identified to its set by figure, color, concept, orientation or by any combination thereof. The images may be generated by means of various known means making use, for example, of lamps, lamps and image-printed transparent film, electroluminescent devices, light emissive diodes, liquid crystal cells, or the like.

DETAILED DESCRIPTION OF THE INVENTION The time indication method that results in the novel timepiece of the present invention provides at least two modes of time indication for the designers selection, as follows:

1. The number of images present and belonging to the first set of images indicates the hourly segments in designation of the time, and the number of images present and belonging to the second set of images indicates the minute segments in designation of the time; or

2. The number of images present and belonging to the first set of images indicates the hourly segments in designation of the time, the number of images present and belonging to the second set of images indicates the IO-minute segments in designation of the time and the number of images present and belonging to the third set of images indicates the minute segments in designation of the time.

Referring now to the drawings, and in particular to FIG. 1, images 1 of blue sail boats belonging to the first set, images 2 of yellow fish belonging to the second set, and images 3 of red crabs belonging to the third set are to be generated on the indicating panel 4. Each image has explicit identification to its setby color and concept. Assuming that the hatched images are present and the others have faded away (that is, not present), the timepiece indicates the time 4 35.

Throughout the present specification, the same reference numerals are used to designate similar elements of the invention for ease of understanding and description.

Referring to FIG. 2, images 1 of blue spades and clubs in a clear background belonging tothe first set, images 2 of red hearts in a blue background belonging to the second set and images 3 of red diamonds in a blue background belonging to the third set are to be generated on the indicating panel 4. Each image has explicit-identification to its set by color and concept.

Referring to FIG. 3, images 1 of lilies in white square backgrounds belonging to the first set, images 2 of birds in yellow round backgrounds belonging to the second set and images 3 of squirrels in green round backgrounds belonging to the third set are to be generated on the indicating panel 4. Each image has explicit identification to its set by concept and by color and the hourly and minute designating images have explicit identification by the configuration of the background shapes.

FIGS. 4 to 6 show the time vs. pattern of the image array relation for the embodiments of the timepieces of FIGS. 2 and 3. In FIG. 4 (I), (II), (III), (XII) indicate one oclock, two oclock, three oclock, twelve oclock, respectively. In FIG. 5 (I), (II), (III), (IV) and (V) indicate one ten-minute interval, two l0- minute intervals, three IO-minute intervals, four 10- minute intervals and five IO-minute intervals, respectively. In FIG. 6 (I), (II), (III), (IX) indicate 1 minute, 2 minutes, 3 minutes, 9 respectively.

These particular patterns of image arrays of FIGS. 4 to 6 are determined based on the following consideration:

l. Easiness in counting images;

2. The pattern of image array clearly indicates the number of images present and eliminates the possibility of misreading; and

3. Easiness in finding lamp failure when it occurs.

For the embodiments of the timepieces as shown in FIGS. 1 to 3, such indicating panel assemblies as shown in FIGS. 13 and 14 may be used.

Referring to FIG. 13, a sheet of image-printed transparent film 8 is placed behind a front cover 6 of clear glass or plastic plate having a translucent back surface 7. A set of lamps 10 and sockets 11 fixed on a base plate 12 are provided, one lamp for each image print of the film. A mask 9 having apertures and skirts is placed behind the film.

Referring to FIG. 14, which shows an alternative arrangement, a sheet of translucent film 14 having a semi-reflective back surface is placed between a front cover 13 of clear glass or plastic plate and a sheet of image-printed transparent film 8. The mask 9 divides the areas and isolates the lit panel sections from each other, as in FIG. 13. The lamp l0 and socket 1] arrangement of FIG. 14 is also similar to that of FIG. 13 described above.

The image-printed transparent films for the embodiments of the timepieces of FIGS. 2 and 3 are interchangeable because the two embodiments have identical patterns of image arrays. Interchangeability of image-printed transparent films is extremely valuable from the commercial view point, because it provides a practically unlimited range of mode selection for users, while at the same time minimizing the range of timepiece models.

Referring to FIG. 7, images 1 of green round spots belonging to the first set, images 2 of orange round spots belonging to the second set and images 3 of red round spots belonging to the third set are to be generated on the indicating panel 4. Each image has explicit indentification to its set by color. Assuming that the hatched images are present or visible (i.e., illuminated), the timepiece indicates the time 3 z 26.

Referring to FIG. 8, images 1 of green diamonds belonging to the first set, images 2 of red hexagons belonging to the second set and images 3 of red diamonds belonging to the third set are to be generated on the indicating panel 4. Each image has explicit indentification to its set by figure and color. Assuming that the hatched images are present, the timepiece indicates the time 4 15.

Referring to FIG. 9, images 1 of green squares belonging to the first set, images 2 of twin diamonds, the top one being red and the bottom one being green, belonging to the second set and images 3 of red diamons belonging to the third set are to be generated on the indicating panel 4. Each image has explicit identification to its set by figure and color. Assuming that the hatched images are present, the timepiece indicates the time 2 32.

Referring to FIG. 10, images 1 of oblique green rectangles belonging to the first set, images 2 of horizontal yellow rectangles belonging to the second set and images 3 of vertical green rectangles belonging to the third set are to be generated on the indicating panel 4. Each image has explicit identification to its set by color and orientation. Assuming that the hatched images are present, the timepiece indicates the time I 44.

Such images as shown in FIGS. 7 to 10 may preferably be generated by means of solid state illuminants, e.g. light emissive diodes, resulting in a compact jewelry-like indicating panel that is particularly suitable for a wrist watch.

Referring to FIG. 11, images ll of blue squares belonging to the first set and images 5 of rose-colored round spots belonging to the second set are to be generated on the indicating panel 4. Each image has explicit identification to its set by figure and col0r. The images 1 may preferably be generated by means of electroluminescent devices, such as electroluminescent panels, and the images 5 by means of miniature lamps. Assuming that the hatched images are present, the timepiece indicates the time 3 37.

FIG. 12 shows the time in hours vs. pattern of image array relation for the embodiment of the timepiece of FIG. 11. (I), (II), (III), (XII) indicate one oclock, two oclock, three oclock, l2 oclock, respectively.

FIG. 15 shows a typical indicating panel assembly making use of liquid crystal cells. The liquid crystal cell assembly is comprised of a pair of clear glass plates 18 and 20,, each plate having transparent and electrically conductive coatings on the counter-facing surfaces thereof, and nematic liquid crystal 19 held between the plates. A liquid crystal cell is placed behind each aperture of a mask 17. The cells are further protected with clear plates 16 and 22. A sheet of image-printed transparent film 8 is placed between the liquid crystal cells and a mirror 23. The timepiece is viewed from the side of clear plate 16. The liquid crystal cell is translucent when an electric field is applied across it and is transparent when the electric field is gone. Image prints of the film 8 are visible by external light when the corresponding liquid crystal cells are transparent. Thus, the image generation is controlled by the electric field applied to the conductive coating on the plates 18 and 20. Spaces 21 for wiring are provided between the liquid crystal cells.

FIGS. 16 and 17 belonging together show the schematic wiring diagram of a typical image generation controller particularly suitable for the embodiments of the timepieces shown in FIGS. 2 and 3. The lamps 34 for generating images 1 of the first set are controlled by means of rotary cam switches 31 driven by a pulse motor M1. Likewise the lamps 35 for generating images 2 of the second set and the lamps 36 for generating images 3 of the third set are controlled by means of rotary cam switches 32 and 33, respectively. Cam switches 32 and 33 are driven by respective pulse motors M2 and M3. The timing pulses to drive the pulse motor are generated by means of switch S,,, and cam 28 driven by a synchronous motor 29, as shown in FIG. 16.

The following nomenclature is employed in connection with the diagram shown in FIGS. 16-19 of the drawing: R-relay coil; and r-relay contact. Subscript s: l Pulse Generator Lock Relay; 2 Holding Relay; 3 Unlock Relay.

When adjusting the time for the embodiment of FIGS. 16 and 17, the user shifts the contact of selector switch SS from normal position 1 to position 2 and waits until pilot lamp lights. The pilot lamp lights when the synchronous motor 29 is disconnected immediately after the first timing pulse in the time-adjusting operation is sent out. Then the user repeatedly pushes push button PB as many times as necessary until the right number of images of the third set appear. The user then shifts the contact of the selector switch SS, to position 3 and pushes push button PB as many times as necessary until the right number of of images of the second set appear. Likewise the contact of the selector switch SS is then shifted to position 4 and the number of images of the first set is adjusted by depressing push button PB Then the contact of selector switch S5 is returned to normal position 1.

A pair of lamps a and 35b are provided at the third position of the second image set so that lamp failure would not cause misreading of the time. Lamp failure at other positions will be easily found because of unusual patterns of the image array.

The present invention may be applied to a centralized timekeeper system having a plurality of secondary clocks. For this application, the timing pulse generator is eliminated in the image generation controller of each secondary clock.

FIGS. 18 and 19 belonging together show the schematic wiring diagram of a typical image generation controller particularly suitable for an embodiment of the timepiece shown in FIG. 7. Solid illuminants 37 such as light emissive diodes for generating images 1 of the first set are controlled by means of cyclically operable stepping switch (FIG. 18), or an equivalently functioning solid state switch circuit, and diode matrix 44, the row conductors of which are connected to the outputs of switch 40. Likewise illuminants 38 for generating images 2 of the second set and the illuminants 39 for generating images 3 of the third set are controlled by means of cyclically operably stepping switches 41 and 42 and diode matrices 45 and 46 respectively.

Adjustment of the time in minutes, in ten-minutes and in hours is performed using push buttom PB at contact positions 2, 3 and 4 of selector switch S8,, in a similar manner as in the embodiment of FIGS. 16 and 17. llluminant failure can be examined using PB, and PB,. The power source V can be disconnected by S,,, and pilot lamp 43 indicates connection of the timing pulse generator 47 to the power source.

In this embodiment, images are generated only at the desired time by depressing push button PR so that power consumption is minimized.

In the typical image generation controller shown in FIGS. 16 and 17, the pulse motors M M and M are of the type wherein the shafts thereof are advanced a predetermined vocational distance in response to each timing pulse. The shaft of the motors are attached to rotary cam switches which are selectively activated, in accordance with the arrangement of the cams, for each advancement of the motor responsive to each pulse. It should be clear that other types of motors and switch arrangements could be used. For example, a well known type of stepping switch which changes its switching configuration upon receipt of input pulses,

could be used.

In FIG. 16, the terminals K and K are coupled to a source of power.
